I have a RadGridView with GridViewCheckboxColumn.

When  I click on any cell in the grid I catch the CellClick event of the grid and   check/uncheck the checkboxcolumn in the specific current row.

It work fine in all the cells except for click on the checkbox cell that do change the value but  the result doesn’t appear in the checkbox.

 The changes are seen only after I move the cursor.

How it is possible that the value is changed but the checkbox isn’t checked/ unchecked ?

  void RadGridView_CellClick(object sender, GridViewCellEventArgs e)

        {

            if (e.RowIndex > -1)

            {

                if (e.Row.Cells["Sel"] != null)

                {

                    if (e.Row.Cells["Sel"].Value != DBNull.Value)

                        e.Row.Cells["Sel"].Value = !Convert.ToBoolean(e.Row.Cells["Sel"].Value);

                       

                    else

                        e.Row.Cells["Sel"].Value = true;

                       

                }

            }

           

        }

For RadDateTimeEditor, I have the following question, Anyone can help me?
Now in the standard RadDateTimeEditor, We have to type value with a format of 'YYYY/MM/DD'
That means if we want to type '20150201', we have to type '2015/02/01' or '2015 02 01'.

But my clients have the following requirements.
He wants to type a value with a format of 'YYYYMMDD', that means he wants to directly type a value '20150201'.

So, Is there any way or any code to do that.
Thanks

Hi,

Is there a way to set the input (TextBox) control of the GridViewDateTimeColumn to ReadOnly or Enabled = false?

We would like to have the user select the date from the drop-down calendar only.  And not allow anything to be entered into the TextBox.

Thanks,

Mike

I whish to add a track bar or range selector to a group in a Ribbon bar at design time.  I cannot figure out how to do this.  Optionally, how would I do this with Code(C#)?

In UI for WinForms, I'm having trouble understanding how to link a RadTextBoxControl to a database containing ~ 60,000 part numbers.  Obviously I don't want to fetch the whole list into RAM, I want to query the db every time the user types a character.  What event do I trigger on to refresh the list, and how do I specify the query itself (search parameters, number of results returned, etc.)?

I've tried binding the .AutoCompleteDataSource to a List<string> and updating that list via the database every time the TextChanged event fires, but it doesn't work - updating the datasource doesn't re-bind to the control, and setting the property again seems to wipe out any autocomplete in progress.



Are there any code examples of using autocomplete function bound to a database?

Thanks,
Randy

Hi,

I don't have any experience with Telerik Controls and have not done much research on Telerik controls.

Can anyone advise if GridView control for WinForm has the capability to support drag and fill across rows within one column? Basically we want the data grid control have full some Excel-like capability to manipulate data (like Drag & Fill within one column, Drag and Copy etc..).

Thanks,

Hello,

Here is my problem. I've an c# application and a website both with telerik's tools.

I've got a web page to create a radtreeview. The xml of this radtreeview is stored in my database and i'm using it to load in different pages.

I'm also using it to load a radtreeview in my c# application. 

What I need now is to allowed my customer to move nodes in the radtreeview (in my application, in the web it's working great), and save this new radtreeview (xml) in my database...

The xml is totally different between winforms and ASP.NET and my radtreeview is wrong in the web after i save the xml from my application.

Is there a fast solution to link RadTreeView from winforms and RadTreeView from asp.net ? 

Thanks,

Regards.

Hello, 

I use OS: Win 8.1
         .Net4.5
        UI fo Winforms Vers. 2014.2 715 

I try to make a relation between 2 tables in my MS Entity (Framework 6.0.1),

The problem is the tables don't have a column in common so that i can make a direct relation,

What i need is a possibility to .Join a third table to my parent which provides the missing column.

My 3 tables are

tbl_AffiliateCommision which should be my parent template in the Hierarchygridview this table provides me the column "AffiliateUser" and the grouping would be done with this column.

tbl_Affiliate in this table every AffiliateUser gets his specific "IdAffiliates". This table would provide both columns. This table should not be shown in the grid

ItemAffiliate which should be the child template and  provides me the sold items and the column "IdAffiliate" which is a undergroup of the Column "AffiliateUser" ( AffiliateUser is not available in this table)

e.g.: AffiliateUser : 12354 has the IdAffiliates: 1,4,6
         AffiliateUser: 32145 has the IdAffiliates: 2,3,7

Here some code for better a understanding 

in the 01 line i just look up the data i would use the same Join in teh 02 line if it would work like this. 
the rest of the code shows how i would make my grid.

Please let me know if i forgot to give you important information.



best regards
